7th Grade (SCI) Life Science Standards [LS4] Biological Evolution: Unity and Diversity
SCI-MS.LS4.06 Use mathematical representations to support explanations of how natural
selection may lead to increases and decreases of specific traits in
populations over time.
Clarification Statement: Emphasis is on using mathematical models, probability statements, and proportional reasoning to support
explanations of trends in changes to populations over time. Disciplinary Core Ideas LS4.C: Adaptation
Adaptation by natural selection acting over
generations is one important process by which
species change over time in response to
changes in environmental conditions. Traits
that support successful survival and
reproduction in the new environment become
more common; those that do not become less
common. Thus, the distribution of traits in a
